One kind of three mode sine wave controller

[leafmotor]

This Brand New electric motor controller with Sine wave, Square wave, No hall, three modes compatible.

What are three modes?
* First mode: Sine Wave Status - Motor without noise,Very quiet !
If one of motor hall sensor is broken, controller still can work in Sine Wave Status.

* Second mode: Square wave Status - Motor with a little noise, < 60db, speed is about 8% faster than Sine Wave Status.
If two of motor hall sensors are broken, controller can work in Square Wave Status.

* Third mode: No hall Status - Motor with a little noise, < 60db, speed is about 8% faster than Sine Wave Status.
If all of three hall sensors are broken, controller can work in No hall Status.

If your motor's hall sensors are broken, don't need to replace hall sensors. Just use this controller that can recover your motor to work.

If you don't know how to match motor wires to controller.
Just plug two blues together, controller into learning status and looking for correct working way. After 1-2 seconds, it can find correct working way,then disconnect these two blue wires' plugs. From now on,it always works with this kind of correct way.
